Build Failed: UBT does not exist

Trying to use the ProjectLauncher to build and deploy an executable in Win64. The build step immediately errors out with this:
BUILD FAILED: UBT does not exist in C:\Users\MRoac3\Documents\Unreal Projects\Engine\Binaries\DotNET\UnrealBuildTool.exe.

Which is correct, that’s not where the UnrealBuildTool.exe is on my machine.
What setting do I change to point Unreal to the proper directory:
C:\Program Files\Epic Games\UE_4.26\Engine\Binaries\DotNET

Figured it out. It was an environment variable uebp_LOCAL_PATH that was hard-coded to C:\Users\MRoac3\Documents\Unreal Projects.
I had removed the environment variable, but needed to refresh my terminal and/or restart Unreal to see the change.
